GNOME Mahjongg

A solitaire version of the classic Eastern tile game. Tiles are stacked on
the board at the start of the game. The goal is to remove all the tiles in
as little time as possible. Select two matching tiles and they will disappear
from the board, but you can only select a tile if there is an empty space to
its left or right at the same level. Be careful: tiles that look alike
may actually be slightly different.

GNOME Mahjongg features a variety of starting layouts, some easy and some
difficult. If you get stuck, you can ask for a hint, but this adds a large
time penalty.
